I'm quite happy with my class d amps. Yes the manufacturer offers upgrades at a not so out of site price. Yes i have upgraded twice, Yes each time my amps have increased in there ability to make music better. And yes i use a tubed preamp for now with my class d amps. A bit of the old with the new. For the life of me i cant understand why some have to believe that what they like is the only thing thats any good. Guys and gals if you have a amp and system thats to your liking i am so glad for you. Dont argue that its better than mine.
Enjoy your system and i will enjoy mine.
